Tree volume is one of many parameters that are measured to document the size of individual trees. Tree volume measurements serve a variety of purposes, some economic, some scientific, and some for sporting competitions. Measurements may include just the volume of the trunk, or the volume of the trunk and the branches depending on the detail ...
Volume can be calculated from the metrics recorded in a plot sample. For example, if a tree was measured to be 20m tall and with a DBH of 19 cm using previous measured tree data a volume could be approximated according to species. Such a table has been constructed by Josef Pollanschütz [4] in Austria. Volume of tree = BA X h x f pollanschutz
Tree volume measurements may include just the volume of the trunk, or may also include the volume of branches. [25] Volume measurements can be achieved via ground-based or aerial methods. Ground-based measurements are obtained by the use of a monocular w/reticle, laser rangefinder, and a clinometer.
A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...
Tree shape profiles can be calculated individually for each tree encountered. However, examining the profiles of a large number of trees of different species found that typical profiles varied in a regular pattern, and for each profile family there was a Crown Form value that could be used to calculate the volume of the crown.
There are different tree species compositions in each region in the world and most of those regions have at least one equation that estimates tree volume from DBH. Research and the application of forest allometry have meshed over time to develop these quick equations to accurately estimate how much volume a particular forest stand holds.

Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...
